Definitions
- This line of contact is on the edges of the fixed bearing plates located at the front and rear of the mounting plate.
- This characteristic of the fixed bearing plate causes a plowing action between the bearing plate and the feed column and accelerates wear of both the feed column and bearing plate.
- This wear comprises a major maintenance factor in drilling equipment.
- Presently existing systems typically harden the fixed bearing plates to reduce wear, thus making the bearing plates much harder than the feed column. While this may improve wear of the bearing plates, wear on the feed column is not improved.
- an apparatus for reducing the amount of wear between the bearings of a mounting plate and the feed column of a drilling rig is needed.
